摘要
切纸机广泛应用于各种办公环境,其机身稳定性对其使用性能影响较大。基于此,对QZ920B型切纸机进行参数化建模,并利用ANSYS对整机进行静力分析,以得到机身各结构的受力和变形情况。利用逆向工程概念,以静力分析结果为依据修改参数化模型,并对优化后的模型做模态分析,得到其5阶振动模态图。通过分析新结构的稳定性,得知优化后的结构应力下降了5.95%。
Paper cutters are widely used in various office environments today,and the stability of their fuselage has a greater impact on performance.Based on this,the QZ920B paper cutter is modeled with parameters,and ANSYS is used to make a static analysis of the whole machine to obtain the force and deformation of each structure of the fuselage.Using the concept of reverse engineering,the parametric model is modified based on the static analysis results,and the optimized model is modal analyzed to obtain its fifth-order vibration mode diagram.By analyzing the stability of the new structure,it is known that the stress of the optimized structure is reduced by 5.95%.
